AI Article Synopsis
- Researchers used EPR dosimetry to measure radiation doses in teeth from people living near the Semipalatinsk Nuclear Test Site due to radioactive fallout.
- The study reconstructed doses for 103 individuals, revealing most "accident doses" ranged from zero to around 2 Gy, with one individual receiving a higher dose of about 9 Gy.
- The findings indicated variations in radiation exposure linked to differing fallout distribution and residents' lifestyles, with average gamma doses for villagers between a few tens of mGy to about 100 mGy.
Article Abstract
The determination of external dose to teeth of inhabitants of settlements near the Semipalatinsk Nuclear Test Site (SNTS) was conducted using the EPR dosimetry technique to assess radiation doses associated with exposure to radioactive fallout from the test site. In this study, tooth doses have been reconstructed for 103 persons with all studied teeth having been formed before the first nuclear test in 1949. Doses above those received from natural background radiation, termed "accident doses", were found to lie in the range from zero to approximately 2 Gy, with one exception, a dose for one person from Semipalatinsk city was approximately 9 Gy. The variability of reconstructed doses within each of the settlements demonstrated heterogeneity of the deposited fallout as well as variations in lifestyle. The village mean external gamma doses for residents of nine[ settlements were in the range from a few tens of mGy to approximately 100 mGy.

Cadmium is a non-essential element and neurotoxin that causes neuroinflammation, which leads to neurodegenerative diseases and brain cancer. To date, there are no specific or effective therapeutic agents to control inflammation and alleviate cadmium-induced progressive destruction of brain cells. Fluoroquinolones (FQs), widely used antimicrobials with effective blood-brain barrier penetration, show promise in being repurposed as anti-inflammatory drugs.

Background: Breast conservation therapy for patients with DCIS includes breast conserving surgery (BCS) with post-operative radiotherapy (RT). Because RT does not impact overall survival, identifying women who do not benefit from RT would allow de-escalation of therapy. We evaluated the impact of a novel 7-gene DCIS biosignature on adjuvant radiation recommendations for patients undergoing BCS for DCIS.

Aim: To achieve glucose-activated transcriptional regulation of insulin analogue in skeletal muscle of T1D mice, thereby controlling blood glucose levels and preventing or mitigating diabetes-related complications.
Materials And Methods: We developed the GANIT (Glucose-Activated NFAT-regulated INSA-F Transcription) system, an innovative platform building upon the previously established intramuscular plasmid DNA (pDNA) delivery and expression system. In the GANIT system, skeletal muscle cells are genetically engineered to endogenously produce the insulin analogue INSA-F (Insulin Aspart with Furin cleavage sites).

The emerging combination of chemotherapy and radionuclide therapy has been actively investigated to overcome the limitations of monotherapy and augment therapeutic efficacy. However, it remains a challenge to design a single delivery vehicle that can incorporate chemotherapeutics and radionuclides into a compact structure. Here, a chelator DOTA- or NOTA-modified Evans blue conjugated camptothecin molecule (EB-CPT) nanoprodrug was synthesized, which could self-assemble into nanoparticles due to its inherent amphiphilicity.
